Increased compatibility

A source media file can be transcoded to formats (such as MP4 and HLS) that are compatible with more types of devices for smooth playback.

Increased bandwidth compatibility

A source video can be transcoded for output in multiple definitions such as LD, SD, HD, and FHD. End users can select the most appropriate bitrate depending on their network conditions.

Improved playback efficiency

The moov atom can be moved from the end of an MP4 file to the beginning of the file, allowing the video to be played before it is entirely downloaded.

Watermarking

A watermark can be added to a video to mark video ownership or copyright.

Opening and ending credits splicing and clipping

Content such as ad and promotional material can be added to a video as opening or ending credits.

Reduced bandwidth usage

With a more advanced codec (such as H.266 and AV1) or transcoding mode (Top Speed Codec transcoding), the bitrate of a video can be substantially reduced while retaining the original quality, which helps reduce the bandwidth usage.
